TO ALL WHOM IT MAY- CONCERN:

Be it known that I, JESSE P. BARRICK, of Massillon, in the county, of Stark, and State of Ohio, have invented certain new and usegul improvements in Garriage-Shaft Couplings; and I do .hereby declare that following is a full and complete description of the same, reference being had to the accompanying drawings, the making a part of this specification, in which Figure 1 is a top view of the coupling.-

Figure 2 is a front view.

Like letters of reference refer to like parts in the views.

In fig. 1, A represents the axle-tree to which the coupling is attached by means of the clip 13. Said coupling consists of'tbe stay 0, between the cheeks of which is secured the reach or thill-irons D, by means of the bolt E, all of which isor may be constructed in the ordinary way. In order to prevent the bolt from working out, and thus let loose the reach from the stay, a check, F, is attached to the axle-tree, close to the coupling, as shown in the drawing. This check consists of a case or shell, G, fig. 1. This shell is attached .to the axletree by means of a thin tongue, II, passed between the wood and axletree, asindicated by the dotted lines. In the bottom of this box is fixed a spring, I, fig. 2, also indicated by the dotted line a, fig. 1. At the corner :1; is pivoted a step or foot, J, which is shown in this figure as being closed, with the foot, as will be seen, resting against the head of the bolt E, and which is thereby prevented from working out and thus detaching the thills from the carriage, therefore dispensing with the use of nuts for retaining the bolt in place, which, as is well known, are always liable toejar and come off, and thereby cause a detachment of the thills, which not-unfroc uently is attended with imniinent danger and great inconvenience. The stop is prevented from being thrown back by the bolt, as shown in fig. 2, by means of the spring I referred to, which is so arranged that it lies parallel with the leg K ofthe stop or foot, and holds it by pressing on the leg on the opposite side of the pivot. The pivot in this instance acting as a fulcrum and the leg as a lever, to the long arm of which is fixed the foot, and upon the short arm is exerted the strength of the spring, the stop can be thrown back by overcoming the strength of the spring, which is only suflicient-ly strong to resist the bolt; hence it can be moved with little trouble, which is sometimes needtul, for the purpose of changing the thills for a pole or a pole for a pair of thills. The stop may be hinged so as to turn up and down vertically, instead of horizontally, as shown, but I prefer the-manner set forth. This check can be applied to any carriage using the ordinary coupling, and for other similar purposes.

What claim as my improvement, and desire to secure by Letters Patent, is-

The pivoted or hinged stop J and spring I, arranged in relation to the coupling in the manner and for the purpose substantially as set forth.
